Astikor Carts

I’m pulling a storage cart with a donkey, her name is Jenny and she’s the LOML ❤️

I have hauled enough coal as well as gravel on multiple occasions, full capacity. My inventory and backpack full + the donkey chest + the entirety of the cart storage. No problems ever.

Today we were trailblazing a path from home base down to the kaolin mansion, the cart was not even half way full of logs- I cut down trees to make a generally straight shot pathway to the destination but I try to store up as much wood as I can along the way for bridge construction- and I noticed that she has the hunger debuff. Doesn’t slow us down at all and she has no hunger bar so it’s a nothing effect as far as I’m aware. I threw a few more stacks of logs in the cart and we won’t move. She can move if I move some stacks of logs from the cart to the chest she has on her body.

What in wondering is why with logs and not a fully loaded gravel or coal cart causes her to become overloaded. And maybe if I start pulling with the white stallion I found earlier I could haul more logs?

TLDR: do different beasts of burden have different weight capacities for pulling the carts and if so what beast is best? A mule perhaps?
